Monkeypox – what do we know about the virus, and how can we treat the disease?

Monkeypox – what do we know about the virus, and how can we treat the disease? The monkeypox virus has been studied, and its mechanism of replicating and invading human cells are understood. Due to prior research on orthopoxviruses, there is a test currently available for diagnosing monkeypox. Additionally, antiviral therapies are currently under investigation. Finally, a monkeypox vaccine is approved and available for individuals at high risk for contracting the virus. While monkeypox treatment options continue to be studied, a variety of medical resources currently exist for high-risk individuals as well as those who were recently exposed to monkeypox.

Our research focuses on how obesity and aging reshape immune responses and lead to inflammatory diseases. Immune cells are sensitive to their metabolic environment, which affects intracellular metabolism and signaling and fine-tune immune functions. We are interested in understanding how metabolic cues regulate communication between immune cells, focusing on dendritic cells and T cells. Our Lab studies how obesity and aging disturb the immune and metabolic balance and lead to excessive inflammation, including diseases such as psoriasis and asthma. We decode molecular mechanisms that link dendritic cell metabolism to tissue inflammation by combining mouse models of inflammatory skin and lung diseases with systems immunology approaches.

Immunometabolism in obesity and aging

Monkeypox – symptoms, transmission, and prevention

Monkeypox – symptoms, transmission, and prevention. Since the 1970s, there has been a steady rise in monkeypox virus cases. While the Orthopoxvirus genus is no stranger to the United States, the specific virus responsible for the monkeypox outbreak has largely been found in African countries, until recently. The geographic footprint of the virus and age of those contracting the disease has steadily expanded. While the epidemiology and symptoms associated with monkeypox are complex, the Centers for Disease Control (CDC) and World Health Organization (WHO) have multiple resources to educate us on the disease progression and modes of transmission.
